Re: have a ? 01 DHS
Your caps lock is stuck.
U codes are voltage and data-related. If the battery was low or disconnected, U codes appear.
B0429 - Rear temperature circuit - the door or actuator that sends air to the rear seat console.
P0410 - an emissions fail code and refers to the AIR system - the old "smog pump" idea that supplies fresh air to the exhaust manifolds on cold start in order to quickly light off the cat. Couple of hours and $250 to DIY fix. (Look about 5 threads away from this one - your question was already posted ...................)
The mirror codes are anyone's guess - troubleshooting time.

Re: 2001 DHS code questions
B0429 is so common it's considered a standard feature. Just means that the rear temperature actuator does not have the door in the commanded position. I've been told it does not take much to set this code. Rear seat passengers might not even notice it, but just for the hell of it, run the rear seat temp control up to max and down to min once or twice. Then clear the code and see if it comes back.

Re: 2001 DHS code questions
Since you have so many modules with a U1000 code, I would tend to think it is not DDM related, but some other common denominator. Maybe a common ground?
